Les API WebView pour les annonces mettent les signaux d'application à la disposition des balises de votre CustomTabSession, ce qui permet d'améliorer la monétisation pour les éditeurs Web qui ont fourni le contenu et de protéger les annonceurs contre le spam.
Fonctionnement
La communication avec le SDK Google Mobile Ads ne se produit que en réponse aux événements d'annonces déclenchés par l'un des éléments suivants:
Le SDK Google Mobile Ads facilite la communication en ouvrant un canal postMessage avec le CustomTabsSession fourni par le framework Android.
Prérequis
- SDK Google Mobile Ads 23.0.0 ou version ultérieure
- Une implémentation existante des onglets personnalisés Chrome dans votre application mobile. Consultez Préchauffage et préchargement: utiliser le service des onglets personnalisés.
- Associez votre application mobile à un site Web à l'aide de Digital Asset Links.
Ajoutez la balise
<meta-data>suivante dans votre fichierAndroidManifest.xmlpour contourner la vérification deAPPLICATION_ID. Si vous oubliez cette étape et ne fournissez pas la balise<meta-data>, le SDK Google Mobile Ads génère une exceptionIllegalStateExceptionau démarrage de l'application.<!-- Bypass APPLICATION_ID check for web view APIs for ads --> <meta-data android:name="com.google.android.gms.ads.INTEGRATION_MANAGER" android:value="webview"/>
Implémentation
Dans votre implémentation des onglets personnalisés Chrome, modifiez le code dans le rappel onCustomTabsServiceConnected(). Remplacez newSession() par MobileAds.registerCustomTabsSession(). Cela établit une connexion avec le canal postMessage pour enrichir les tags d'annonce avec des signaux de SDK. Un lien Digital Asset Links est nécessaire pour connecter le canal postMessage. Vous pouvez éventuellement définir le paramètre CustomTabsCallback pour écouter les événements de l'onglet personnalisé Chrome.
Vous devriez toujours pouvoir envoyer des messages à partir de l'CustomTabsSession reçue du SDK Google Mobile Ads, mais le port peut changer lorsque le SDK demande un nouveau canal qui remplace l'existant.
